9 Claims.

This inventio'nrelates to electric refrigerators and more especially tosuch refrigerators particularly adapted for household and domestic use.

. An object of this invention is a removable refrigerator unit includinga mounting board which serves as an insulating closure for the open topof the refrigerator food storage compartment as a support for adepending evaporator, and as a support for a motor, a compressor, acondenser, and a float valve, these last all being enclosed within abufiet top-cover or hood.

A construction of this character is particularly adapted for domesticuse since it is mounted in the .cabinet as a unit, and in the event ofrepairs, can be removed from the cabinet as a unit and replaced by asimilar unit, thus eliminating the necessity of disassembly or repairsat points other than the factory or authorized service stations.

Further, the unit of the invention is simple, neatof appearance,economical and facile of manufacture, and lighter in weight thanconstructions heretofore provided for this purpose.

Still further objects will readily occurto those Fig. 2 is a top planview of a portion of a re-'- frigerator, with the unit in place, and thebufiet top or cover being removed.

Fig. 3 is an end section as if on the line 33 of Fig. 2, with the coverin place.

Referring to the drawings it will be seen that the refrigerator includesa wall having an outer metallic shell l0, an inner metallic shell l2,and an insulating filler ll, of well known constructioni The outer wallis continued for quite some distance above the inner wall and theinsulation, an'd'i provid d with a bullet top or cover It there beingthus formed an enclosed compartment above the top of the refrigeratorproper. The open top of, the food storage compartment inside the wall I2is closed by the unit closure of the inven on and the construction ofthe will now be described.

The unit closure in Part, comprises a horizontal support 2Q, whichincludes two sheet metal plates 22 and 24 from each other by the flllerof insulating material indicated. The ,lower plate hasaperipheralretaining flange 25 and rests upon a gasket 26 and uponthe outturnededge 28 of the wall l2. The upper plate 1. e e i e n a c sk disposedupon the sheet metal plate 32 which covers insulation ll.

The horizontal support also includes wooden blocks, two of which areshown at 36, these serving to support the evaporator, and to secure all15 of the parts of the horizontal support together. Being of wood, theyprevent heat transfer between plates 20 and 22. These wooden blocks aresecured to the upper plate 22 by screws 38 and have vertical bores 39passing therethru and terminating in counterbores 40 beneath the plate42, the bores being spaced from or staggered with respect to the screws38, as can be readily seen from Fig. 2.

Passing, thru the bores 39 and having their heads 42 resting upon thelower surface of the, counterbores 40, are screw bolts 44 which serve assupports for the depending evaporator 46, the latter having its boiler48 provided with brackets 50 thru which pass the lower ends of the boltsM, there being nuts 52 threaded onto these bolts to secure theevaporator in place.

The upper plate 22 of the horizontal insulating support is provided witha plurality of (four) depressions 56 in which are loosely disposedresilient mounting blocks or spheres 58. These balls, which arepreferably of rubber, are received in raised portions 60 of the parallelrails 62. to which the motor-compressor 64 is secured, the balls thusserving as resilient floating supports. for the motor-compressor unit.

A float valve 68 also rests on the plate 22 and is connected to thecondenser 10 which also rests upon the plate 22, all of these parts andtheir connections being within the peripheral flange 29 of the upperplate 22. i

I In order to hold down the motor against vibration suitable means areprovided and one form of such means is illustrated. Inthis form,stirrups '|6 are secured to the plate 22, outside of the 49 rails 62.Transverse bars or straps l8 resting on and straddling the rails 62 havetheire'nds disposed in the stirrups l6 and pressure is brought on thesebars by screws which thread thru the stirrups and against'the ends ofthe bars 18 to bear down upon the latter and consequently upontherailsto'which is secured the motor.

a, For convenience in lifting the unit outof the refrigerator when thetop It is removed,'baillike handles'82 are secured to the peripheral 60flange 29 at the ends of the lattenas can be seen on the drawings. Fromthe foregoing, it will be observed that there has been provided a unitclosure construe tion for the open ton of a refrigerator eabinet. I

the construction being in the nature of a one piece or unit closure andmounting which has all the advantages previously set forth.

Now having described the invention and the preferred embodiment thereof,it is to be understood that the said invention is to be limited, not tothe specific details herein set forth, but only by the scope of theclaims which follow:-

What I claim is:-
